4635 LPS overview
The Xerox 4635 Laser Printing System (LPS) is a versatile, highperformance printing system that processes and prints data from
a variety of sources. It enables host mainframe computers and
network-connected devices (such as workstations and graphic
scanners) to produce publications and other documents,
incorporating graphics, forms, logos, signatures, and a variety of
fonts.
With the 4635 LPS, management information systems (MIS) and
data processing (DP) environments have a high-performance
printer in which built-in intelligence eliminates the need for the
host computer to store and manage forms, fonts, and other
document resources.
Data is printed at a rate of up to 135 pages per minute (154 with
the optional Paper Feeding Enhancement Kit installed). A variety
of fonts ranging in size from 3 points to 36 points, in all four
orientations (portrait, inverse portrait, landscape, inverse
landscape), and many publishing typefaces are available to meet
your printing requirements. In addition to the standard set of
fonts that is delivered with the LPS, special or customized fonts
can be developed by the Xerox Font Center. Your sales
representative will provide you with further information.
The Xerox 4635MX Laser Printing System (LPS) is the same system
as the 4635 LPS with the addition of Magnetic Ink Character
Recognition (MICR) functionality. Except where explicitly stated,
all references in this document to the 4635 LPS apply to both the
4635 LPS and the 4635MX LPS.

4635 LPS OVERVIEW
4635 LPS
The standard 4635 LPS consists of two main components:
1. System controller
2. Printer.
Figure 1-1 shows the 4635 LPS with the optional bar code
device.
Figure 1-1.
4635 Laser Printing System
The system controller is a minicomputer which manages the
processing of input data; processes operator commands;
provides for the entry and compiling of form, print, and job
description files; executes job processing commands; and
manages low-level control of the printer.
Your 4635 LPS has a PC user interface (PC UI) that enables you
to start and monitor print jobs. In figure 1-1, the PC UI is shown
on top of the system controller.
The printer contains the mechanics and electronics involved in
the imaging and paper handling processes. Touch screen control
on the printer control console allows you to easily monitor and
control printer functions. Jam clearance areas and instructions
are clearly displayed with color graphics.
For more detailed descriptions of the 4635 LPS hardware
components, refer to the “4635 LPS hardware components”
chapter.
Software
LPS software functionally consists of several components to
manage printing system resources. Refer to the “System
software functional description” section of the “4635 LPS
software components” chapter for additional information.
Among these components are two LPS-resident languages: FDL
and PDL.
1-2
XEROX 4635 LASER PRINTING SYSTEM PRODUCT REFERENCE
4635 LPS OVERVIEW
Forms description language (FDL)
(standard)
Print description language (PDL)
(standard)
FDL is a laser printing system resident language for designing
electronic forms which can include logos, signatures, and
shading. Form libraries (source and object) are stored on the
system disks. Refer to the Xerox 4635 LPS Forms Creation Guide
for more information.
PDL is a laser printing system resident language used to describe
the input, logical processing, and output requirements of a print
job. Refer to the Xerox 4635 LPS PDL/DJDE Reference for more
information.
Options
The following options are available to further enhance the
capabilities of your 4635 LPS.
Note: For detailed information regarding these options, please
contact your sales representative.
9-track magnetic tape drive
The 9-track (1600/6250) magnetic tape drive is an alternative or
additional offline capability to the 18-track cartridge tape drive for
inputting print and nonprint data to the 4635 LPS. (Refer to
figure 3-5.)
Refer to the Xerox 4635 LPS Operator Guide and to the LPS
Tape Formats Manual for additional information.
18-track cartridge tape drive
The 18-track cartridge tape drive is an alternative or additional
offline capability to the 9-track magnetic tape drive for inputting
print and nonprint data to the 4635 LPS. It reads and writes IBMand ANSI-compatible half-inch tape in the 18-track IBM 3480 data
format. There is also an option available which allows it to read
and print from the IBM 3490 format.
Refer to the Xerox 4635 LPS Operator Guide and to the LPS
Tape Formats Manual for additional information.
Bypass transport
The bypass transport increases your production capabilities by
providing you with a means of using finishing devices with your
4635 LPS. Conforming to Xerox Document Feeding and
Finishing Architecture (DFA) Level 1 specifications, it allows you
to choose from a variety of finishers.
Input enablement device
The input enablement device provides the means to directly
connect bulk feeders to your 4635 LPS.
XEROX 4635 LASER PRINTING SYSTEM LPS PRODUCT REFERENCE

4635 LPS OVERVIEW
5.25-inch floppy disk drive
The 5.25-inch floppy disk drive is another means of downloading
or backing up files, such as fonts, to the 4635 system disk.
Expanded disk memory
The 4635 has as a standard feature one 651 MB unformatted
system disk, and can support up to three additional 651 MB
unformatted system disks.
Expanded bitmap memory
The 4635 has as a standard feature 32 Mbits of bitmap memory
that supports font and graphics. The bitmap memory can be
expanded to 256 Mbits.
Bar code reader
The bar code reader adds a set of features that allow processing
of bar code data streams. A cross-checking mechanism allows
the 4635 to ensure that any bar code sheets printed have been
accounted for by each component of the software.
Raster image processor
Raster image processor (RIP) performs vector to raster conversion
in support of the Interpress 3.0 Publication Set. It provides
multiple forms capability for any given page and permits printing
of text and image files which would otherwise be unprintable or
incomplete because of complexity. RIP allows you to use two
forms per page and more than 16 graphics on a page for
Interpress applications.
LPS connection
The 4635 may be ordered with the following optional
connections:
Online interface
The online channel interface receives input directly from the host
system. All IBM systems which support the channel-attached
3811/3211 or 4245 interface are supported. Non-IBM systems
are supported through a variety of connections such as DDI.
(Refer to the DDI description below.)
Offline interface
The offline interface is an excellent alternative or addition to an
online operation. It supports 9-track (1600/6250 bpi) and 18track (3480 format) tapes conforming to one of the following
formats:

DDI interface
Ethernet interface
The Dynamic Document Interface (DDI) enables communication
between a 4635 LPS and other products via a shared disk
mechanism. The interface allows the other products (such as
DEC, PC, MAC, and UNIX local area network (LAN) workstations)
to save print files to an external hard disk. The 4635 LPS then
directly accesses the external hard disk to retrieve files for
printing. The DDI passes data over a high performance SCSI bus.
Ethernet is the Xerox local area network (LAN) that allows data to
be transmitted by cable from one device to another. As an
Ethernet member, your LPS can receive and print from other
network “citizens” such as Ethernet workstations and graphic
scanners.
Ethernet workstations
With the Ethernet option, an LPS can receive and print input data
from workstations, such as the Xerox 8010, 6085, and the XPS
700 series. Workstations can transfer Interpress files using
Ethernet to the LPS and invoke LPS-stored forms and graphics for
printing.
Interpress is a page description language capable of describing
any two-dimensional image intended for a raster device, such as
a Xerox LPS. Its function is to describe previously created data
on a page; it is not a page composition language. This
functionality includes vector graphics (sometimes referred to as
line art), contour fonts, and pixel arrays. Interpress also includes
job management features such as paper tray selection, output
offsetting, stock selection, copy count, and page selection on a
copy basis.
An Interpress master can be created at a host or at a workstation
for transporting (offline or Ethernet modes) to the LPS.
Refer to the Xerox 4635 LPS Operations Reference and to the
workstation's documentation for more information.
Ethernet graphic scanners
With the Ethernet option, an LPS can receive and print scanned
graphic data (both line art and continuous tone images) from the
7650 Pro Imager (using the Xerox Publishing Illustrator's
Workstation).
Refer to the Xerox 4635 LPS Operations Reference and the Xerox
7650 Pro Imager Reference Manual for more information.

BASIC CONCEPTS
System controller
The system controller contains the input subsystem and the
control subsystem electronics.
The input subsystem provides interfacing capability (online,
offline, Ethernet, and Dynamic Document Interface (for DEC, PC,
MAC, and UNIX LAN connectivity) for a variety of input sources
(host, magnetic tape, workstations, and graphic scanners).
Note: Your quarter-inch cartridge tape and floppy disk drives are
not input sources for print jobs (refer to the “4635 LPS hardware
components” chapter).
The control subsystem performs all data handling, formatting,
buffering, and operational control of the system. It also provides
operator control through the LPS terminal or PC User Interface
(UI). Refer to the “4635 LPS hardware components” chapter for
more information on system controller components and these
subsystems.
LPS interfaces
The following LPS interfaces are available to connect a variety of
input sources to the LPS:
Offline interface
The offline interface permits input from a computer-prepared
magnetic tape which is loaded onto the magnetic tape drive.
The 9-track and 18-track magnetic tape drives are the optional
offline interfaces available for the 4635 LPS. Refer to the “4635
LPS hardware components” chapter for more information.
Online interface
The online interface permits input from a channel-attached host
computer.
Ethernet interface
DDI interface
The Ethernet interface, using the host interface processor (HIP)
task, permits input from workstations or graphic scanners on a
shared or an unshared, but accessible, network.
The Dynamic Document Interface (DDI) enables communication
between a 4635 LPS and network via a shared disk mechanism
over a SCSI bus. Refer to the Xerox Dynamic Document
Interface Operator Guide for information regarding the DDI.
LPS system disk storage and memory
The system disks store the operating system software (OSS) as
well as the system resources (fonts, forms, and graphics) that are
to be loaded into memory for use during input processing. Refer
to the “LPS software components” chapter for more information
on OSS.

XEROX 4635 LASER PRINTING SYSTEM PRODUCT REFERENCE
BASIC CONCEPTS
Printer
The printer contains the imaging, xerographic, and output
subsystems.
Imaging subsystem
The imaging subsystem accepts a formatted page of data from
the system controller (forms and graphics have already been
merged) for the xerographic process:
Xerographic subsystem
One of the important keys to LPS print quality lies in the
xerographic process itself. The print image produced by the dry
ink is very dark to create more contrast between the printing and
the page, making images easier to read.
The following steps describe the xerographic process:
1. A band full of video data (1s and 0s) is transferred from the
band buffer to the laser scanner.
2. The laser beam moves across the surface of the
photoreceptor belt based on the value of the incoming bit (1
or 0), producing a latent image.
In this step, a charge is applied to the surface of the
photoreceptor belt. The surface is discharged when it is
exposed to the laser beam, thus creating a pattern of dots
corresponding to the page that is to be printed.
3. The photoreceptor belt is then exposed to dry ink. The dry
ink clings to the pattern of dots corresponding to the page
that is to be printed.
4. A sheet of paper traveling along the paper path is brought
into contact with the surface of the photoreceptor belt. The
dry ink is then transferred from the photoreceptor belt onto
the paper.
5. The paper carrying the pattern of dots passes through a
fusing mechanism that permanently affixes the dry ink to the
paper.
6. The finished page is deposited in the output tray or bin. The
data from that page is erased from memory. The
photoreceptor belt is then cleaned and prepared for the next
page.
Resolution
An LPS imaging system converts a character from digitized form
into a printed image composed of tiny dots. These dots are so
small and close together that they appear to form solid black
areas. Image clarity is determined largely by the resolution or the
number of dots per inch printed. Within the 4635 LPS Reference
Set, the terms spots, dots, and pixels are used interchangeably.
The 4635 accepts 300 dots per inch (dpi) print data and images
and electronically modifies them to produce 600 dpi print
resolution. 600 dpi input print data is not accepted by the 4635
for printing. References to 300 dpi or 600 dpi apply to both
coordinate axes (300 by 300 dpi or 600 by 600 dpi).
XEROX 4635 LASER PRINTING SYSTEM PRODUCT REFERENCE

BASIC CONCEPTS
Output subsystem
The output subsystem provides paper stacking, report collating,
and sample print capabilities.
LPS production process overview
As illustrated in figure 2-2 below, the process of producing a job
on an LPS can be broken down into three distinct phases: input,
special processing, and output.
Figure 2-2.
Basic processing flow
Each phase is described in the text that follows.
Input
The input phase of job production begins with the collecting and
inputting of data using one of the following sources.
Sources of input for the LPS
Several data input methods are available, as shown in figure 2-3.
2-4
XEROX 4635 LASER PRINTING SYSTEM PRODUCT REFERENCE
BASIC CONCEPTS
Figure 2-3.
Online
DDI interface
Offline
Ethernet
4635 input options
The channel-attached host computer input is received by the LPS
online interface. In an online environment, the system controller
is physically wired to the host computer. The host computer
“thinks” it is communicating with an IBM 3211 line printer and an
IBM 3811 printing system controller, or an IBM 4245 line printer.
The Dynamic Document Interface (DDI) enables communication
between a 4635 LPS and network via a shared disk mechanism
over a SCSI bus. Refer to the Xerox Dynamic Document
Interface Operator Guide for information regarding the DDI.
Magnetic tape input (9- or 18-track) is received by the offline
interface. The LPS Tape Formats Manual describes the tape
format and encryption schemes which a Xerox LPS recognizes.
Input from workstations, such as the Xerox 6085, and graphic
scanners, such as the 7650 Pro Imager (using XPIW), is received
by the Ethernet interface using the HIP task.
XEROX 4635 LASER PRINTING SYSTEM PRODUCT REFERENCE
2-5
BASIC CONCEPTS
Ethernet is the Xerox local area network (LAN) which allows data
to be transmitted by cable from one device to another on a
shared or an unshared, but accessible, network.
Types of data
Data is created at one of the above sources and transmitted to
the LPS. As mentioned previously (refer to the “LPS overview”
section in this chapter), the system controller receives the
incoming data using one of the interfaces for processing. If the
input is print data, a stream of data is sent to the printer for
imaging. If the input is nonprint data, it is stored on the system
disks.
The following types of data can be printed by an LPS:
•
•
•
Variable data
Fixed data
Variable data
Fixed (forms) data
Graphic data (usually merged with variable data or form data).
Variable data changes from page to page; for example, the text
in this document or the numbers in a financial report.
Fixed (forms) data (FRM file) remains constant from page to page
(for example, letterheads and column headings). Forms data
usually refers to information found on preprinted forms or
overlays.
Note: A host-resident forms design software package, such as
HFDL, is required for form generation at a host.
Any form suitable for computer printout can be described and
entered into system storage. Once stored on the system, a form
can be activated by referencing the form's name in the job
source library (JSL) file or job descriptor entry (JDE).
All Xerox laser printing systems have as a standard feature a line
editor utility for the creation and modification of program source
files (FSL and JSL extension files). Refer to the Xerox 4635 LPS
Operations Reference for more information on the LPS Editor.
Forms are entered into the system as data using the LPS Editor.
They are described using forms description language (FDL)
commands to design the form for variable data. These
commands create what is referred to as a forms source library
(FSL) file which, when compiled, becomes an FRM file. Refer to
the Xerox LPS Forms Creation Guide for more information on
creating electronic forms.
Graphic data
Graphic data (IMG file) refers to digitized images (both line art
and continuous tone images) that are to be merged with variable
or forms data. Sources of graphic data include (but are not
limited to): (1) graphic data generated by XPPI/XDGI host-resident
software, and (2) scanned images from the Xerox 7650 Pro
Imager (using XPIW).
Special processing
Special processing features distinguish the Xerox LPS from an
impact printer. By using commands such as RFEED, ROFFSET,
and RPAGE you can specify that certain logical functions
2-6
XEROX 4635 LASER PRINTING SYSTEM PRODUCT REFERENCE
BASIC CONCEPTS
including: switching paper trays, offsetting certain pages or
logically repositioning a page, be performed during the printing
process. Refer to the Xerox 4635 LPS PDL/DJDE Reference for
more information on these command functions.
DJDE
A Dynamic Job Descriptor Entry (DJDE) command enables you to
modify the printing environment dynamically. These commands
are inserted into the input data stream to modify command
characteristics of the existing JDE. DJDEs can take effect on a
report-to-report, page-to-page, and record-to-record basis. Refer
to the Xerox 4635 LPS PDL/DJDE Reference for more
information.
CME
A Copy Modification Entry (CME) command enables you to
replace certain parts of a report with predefined static data on
selected copies or to specify font changes within the variable
data. Refer to the Xerox 4635 LPS PDL/DJDE Reference for more
information.
Output
The final production phase is output. The Xerox LPS provides
powerful finishing and disbursement features. You can have a
true cover-to-cover printing process on any job. This means that
an inventory stock report job could have:
•
Blue card stock front cover, with the title in a 24-point bold
font
•
Forty-nine pages of equipment inventory, with the last page
designed to summarize totals
•
Thirty-seven pages of equipment description, with pricing
information removed and a shaded grid filling all page
columns
•
A matching blue card stock back cover printed on the
reverse side with “END OF REPORT” in a 14-point bold font.
Each copy of the inventory report can be offset in a stacker bin
(no offsetting in the sample tray) for easy identification, with a
routing sheet on top of each offset stack which contains such
information as “Jones and Smith Supplies, Inc.” This particular
feature is useful when individual copies must be separated for
binding or distribution to different groups. By adding the
optional bypass transport and a third-party finisher to your 4635
LPS, you expand your finishing choices for your report to include
options such as making it into a booklet and shrink wrapping it.
Job source library (JSL) files
Print description language (PDL) commands are used to describe
the data layout and provide instructions for data placement on a
page with or without an FDL-created form. The JSL file contains
PDL statements defining the format of the input, processing
requirements, and the format of printed output. When the JSL
file is compiled, it is referred to as a job descriptor library (JDL)
file and is referenced for printing a job.
Within a JDL file, there may be one or more unique definitions
for different processing features, output formats, and tape
XEROX 4635 LASER PRINTING SYSTEM PRODUCT REFERENCE
2-7
BASIC CONCEPTS
formats. Each set of unique definitions represents a job and is
called a JDE or a job.
A JDL (compiled JSL) file containing printing instructions for the
LPS is required to print any job on any configuration. Many
specialized functions can be accomplished with PDL statement
commands. Refer to the Xerox 4635 LPS PDL/DJDE Reference
for specifics.
Several basic JSL files are provided with the OSS; for example,
ENET.JSL is provided for printing Ethernet jobs, ONLINE.JSL is
provided for printing online jobs, a XEROX.JSL is provided for
printing magnetic tape jobs, and so on. To meet specific
application needs, any OSS-supplied JSL can be copied and
modified. All Xerox LPSs have as a standard feature the LPS
Editor utility for the creation and modification of program source
files (FSL and JSL extension files).
Fonts
A font is a character set which has a unique typestyle, type size,
and orientation. Both fixed and proportionally spaced fonts are
available for use on an LPS. Each font character occupies an area
called a character cell. All character cells in a fixed font are the
same width, while character cells in a proportional font vary in
width, as shown in figure 2-4.
Figure 2-4.
Character spacing
Because the length of a line printed with a proportional font is
relatively unpredictable, fixed fonts are used for variable data on
a report to avoid overprinting of forms by variable data.
Proportional fonts are normally used for forms data, such as,
titles, headings, and so on. A business letter is an example of
the use of proportional fonts for variable data. The difference in
line length is illustrated in figure 2-5.
Figure 2-5.
2-8
Character spacing examples
XEROX 4635 LASER PRINTING SYSTEM PRODUCT REFERENCE
BASIC CONCEPTS
Fonts are available in various typefaces (such as, OCR and Titan),
sizes, styles (such as, serif and sans serif), and weights (such as,
medium and bold). The LPS Standard Font Library Font User
Guide lists the standard fixed and proportional fonts.
In addition to typeface, style, and size, a font can be defined by
its orientation:
•
•
•
•
Landscape
Portrait
Inverse landscape
Inverse portrait.
Refer to the Xerox 4850 HighLight Color and 4135 Laser Printing
Systems Font User Guide for specific font information, the Xerox
LPS Forms Creation Guide for using fonts in a form, and the

The standard QIC tape drive (up to 320 MB in streaming mode;
quarter-inch ANSI) provides an alternative source for the loading
and backing up of user files (extension files such as .FRM) and
fonts to and from the system disk. Disk save and restore (DSR)
and system generation (sysgen) functions can be performed from
the quarter-inch tape drive. It is not an input source for print
jobs.
The optional floppy disk drive is located in the front panel of the
system controller. It provides an alternative way of backing up
and restoring system controller rigid disk files.
One 651 MB (unformatted) fixed system disk is provided as a
standard feature. It resides inside the system controller and
stores the operating system, fonts, forms, and general user files
for the 4635. Optionally, up to three additional system disks

The purge tray located at the top of the last feeder/stacker
module is where waste sheets are sent when cleared from the
printer. The purge tray can hold 100 sheets of paper.
Printer control console
The printer control console located on top of the printer
contains the continue, stop, and sample buttons. The console
has a color monitor with a touch-sensitive screen which displays
detailed graphics showing jam clearance instructions and
feeder/stacker status. Printer tasks, such as lowering feeder trays
and stacker bins, can be performed by touching areas of the
console screen.
Optional bypass transport
The ability to increase your production capability by adding
finishing devices to your 4635 is made possible by the Bypass
Transport option. Finishers give you the ability to choose a wide
range of finishing options, such as shrink wrapping and stitching.
The bypass transport processes simplex and duplex jobs and
accepts any type of paper that your 4635 LPS is capable of
handling (refer to the “4635 LPS overview” chapter).
Connected to the feeder/stacker, the bypass transport allows
finishing devices to interface directly with your 4635 LPS. It is
fully integrated into your 4635 LPS hardware and software
utilities, allowing you to select it at the UI or within your job
setup. The bypass transport meets the Xerox Document Feeding
and Finishing Architecture (DFA) Level 1 specifications.
Optional input enablement device
The input enablement device is connected to the right side of
the feeder/stacker module and provides the means to add bulk
feeders to your 4635 LPS. Fully integrated into your 4635 LPS

4635 LPS software
components
This chapter describes the software components associated with
the 4635 Laser Printing System (LPS). The major topics are as
follows:
•
•
•
LPS operating system
Operating System Software (OSS) functional description
Optional host-resident software packages.
LPS operating system
The 4635 System Software consists of the Xerox OSS, System
User Interface (UI) Software, User Interface Dialog, and the
Printer Software. The OSS is the primary software; however,
each software type working in conjunction controls and monitors
the operation of your 4635 LPS.
The LPS OSS, like any other operating system, is a set of
programs which allow the printing system to manage its own
resources. Xerox distributes new versions of the 4635 OSS on 9track, 18-track cartridge, or quarter-inch cartridge tape. The OSS
tape contains:
•
New system files
•
A system generation processor program that is used to load
the new system files onto the system disks and configure
them for a particular system
•
A concatenated version of the system files and system
generation processor which is used for performing an online
system generation (wherein the processor and files are
downloaded to the printing system from a host computer)
•
Patch files which are used to modify the new system files for
optimal performance.
Refer to the “System software functional description” section of
this chapter for more details on OSS contents.
The process by which the OSS is installed, upgraded, or modified
is called system generation or sysgen. There are three types of
sysgens that can be performed: mini, update, or full.
•
In a mini sysgen, an existing operating system is modified in
a way that does not require new system file input or
patching. For example, an existing feature is deactivated or
reactivated, or a specification is changed that is independent
of the operating system files.
•
In an update sysgen, an existing operating system is
upgraded to include new features or is replaced with a new
version of the system.
XEROX 4635 LASER PRINTING SYSTEM PRODUCT REFERENCE
4-1
4635 LPS SOFTWARE COMPONENTS
During this process, some or all of the existing system files
on the system disks are replaced with new files; user files are
not affected.
•
In a full sysgen, a new operating system is built on empty
system disks; that is, new or used disks that have been
cleared and formatted prior to sysgen.
Complete instructions for each of these sysgens are contained in
the Xerox 4635 LPS System Generation Guide.
The UI Software consists of two 3.5-inch floppy diskettes (one
supports the system UI Software, and one supports the UI
Dialog). The Printer Software also consists of several 3.5-inch
floppy diskettes. Refer to the “System software functional
description” section for further information on the System UI
Software, UI Dialog, and Printer Software.
Operating System Software functional description
The LPS OSS, or system controller, runs both background and
foreground processing. All Xerox LPS systems are run by
basically the same software. The OSS is delivered for installation
and sysgen on 9-track magnetic tapes, and 18-track or quarterinch cartridge tapes. The major utilities or “tasks” run by the
system controller are shown in their hierarchical relationships in
the chart below.
Figure 4-1 illustrates the hierarchy of the major LPS processing
tasks. Following the figure is an overview of each task.

XEROX 4635 LASER PRINTING SYSTEM PRODUCT REFERENCE
4635 LPS SOFTWARE COMPONENTS
Operating system executive task
File control program
Operator communication
subsystem
The OSEXEC task is always running. It interfaces with the LPS
hardware and logs hardware errors. In addition, it queues
devices, manages resources, establishes priority for software
tasks, and schedules processing.
The FCP or FMS task manages disk resources. It manages and
allocates all disk space, creates all disk files, and accesses disk
files.
The OCS task acts as an interface between the operator and
software tasks by receiving input from and displaying messages
to the operator. OCS also interfaces between system tasks.
Diagnostic tasks
The OSDS runs either under the OSEXEC task or from offline
sources. It controls the processing for the PROBLEM command.
Diagnostic support is also provided to your service technician by
the stand-alone field engineering software (SAFES) task.
System utilities
The LPS has many utility programs which run under the OSEXEC
task that provide maintenance services such as: backing up the
system (DSR); tracking the unusable sectors on disks (FCHECK);
assigning a maximum size to the working print file
(REALLOCATE); eliminating wasted space on the disks
(COMPRESS); and making used space available again (PURGE).
Editor task
The Editor task creates and modifies disk files. When you save a
work file, it stores the contents permanently on the disk. It
sends files to print; sends FSL and JSL files to be compiled;
directs CMD files to execute; and manipulates temporary (TMP),
miscellaneous (MSC), patch (PCH), and data (DAT) files.
Font Editor task
Input task
The Font Editor task creates and modifies font files. The font
files are stored permanently on the disk when you save them.
The input task reads in print job data, creates a job control block
file, and delivers job messages to the operator. Then the input
task unpacks and converts the data; selects and deletes blocks or
records; records any special processing instructions (for page
offsets, DJDE records, CMEs); and records the disk addresses of
the font, form, and image files used for the job. The result is a
page buffer, consisting of the variable data and print instructions
for the page, and the page log, consisting of tracking information
used to process the page.
Dynamic job descriptor task
The DJD task compiles the Dynamic Job Descriptor Entries
(DJDEs) in the job stream. (The DJDEs give the printer
instructions for printing based on the result of true/false tests of
the data in the job stream.
Interpress decomposer task
The IPD task translates input data sent in Interpress format into
ASCII raster format.
XEROX 4635 LASER PRINTING SYSTEM PRODUCT REFERENCE
4-3
4635 LPS SOFTWARE COMPONENTS
Output task
The output task uses the page logs written by the input task to
load fonts in the font memory and variable data in the CD. It
causes paper to feed from the indicated tray and manages report
integrity with multiple checks. It sends the page buffer
information to the CD and coordinates the activity of the CD/IG
and RIP with the printer. In addition, Output manages delivery of
the printed pages to the correct bins and performs page recovery
if necessary.
Print description language compiler
The PDL task loads the PDL compiler and looks in the JSL library
for the file to be compiled. Then it analyzes the JSL statements
and creates the object module (the JDL file).
Forms description language compiler
The FDL task loads the FDL compiler and looks in the FSL library
for the file to be compiled. Then it analyzes the FSL statements
and creates the object module (the FRM file).
Host interface processor task
Report (RPT) task
The HIP task controls LPS communications with an online host.
It transfers SNA/SDLC or BSC files from the host to the LPS,
storing or printing them as directed. HIP also transfers files from
the host for storage and transfers Interpress files from a Xerox
Ethernet to the LPS for printing.
Works in connection with the Input task.
Printer Software
The Printer Software works in conjunction with the OSS (system
controller) to print your job. The system controller interprets the
user instructions contained in JDLs, DJDEs, and operator input, as
well as the data being printed on each page. The system
controller, driven by the OSS, sends this information to the
printer. Once the information reaches the printer, it is the Printer
Software that identifies the best way to carry out the task.
User Interface Software and User Dialog Software
As with the OSS and Printer Software, the System UI Software
and the User Interface Dialog interact together to control your
PC UI. Along with establishing and managing the
communication between the PC UI and the printer, the User
Interface Software displays the objects on the UI screen and
performs the actions input by the operator, as specified within
the UI Dialog.

Optional host-resident software packages
This section describes a few of the many host-resident software
packages available for use with your 4635 LPS. For information
on a specific program, please contact your site representative.
Xerox Pen Plotter Interface (XPPI)/DCF
and GDDM Interface (XDGI)
Host Forms Description Language
(HFDL)
Xerox Printer Access Facility
(XPAF)
XPPI/XDGI is a host-resident software package (on IBM MVS or
VM/CMS) that translates computer-generated text and graphics
into high-quality images that can be printed on a Xerox LPS. A
host-independent version of XPPI/XDGI is also available for nonIBM users. Refer to XPPI/XDGI documentation for more
information.
HFDL is a host-resident forms design software package (on IBM
MVS or VM) that allows forms to be created, changed, and
merged with data at the host for printing.
XPAF enhances the capabilities and use of your LPS in an IBM
MVS/XA environment. For example, it allows you to change
printer destinations without restructuring the data stream. XPAF
accepts numerous types of data streams, transforms or
conditions them, and then sends them to the selected printer.
To users of IBM Advanced Function Printing (AFP), XPAF appears
to be an extension of the IBM product.

4635 LPS SOFTWARE COMPONENTS
Xerox Print Services Manager
(XPSM)
XPSM is the IBM RS/6000 based software product that acts as a
server to provide communications access to clients, catalog
printer-resident resources, and spool print jobs for Xerox laser
printers. XPSM also provides context-sensitive help files that are
accessible through the graphical user interface.

Product differences/user
considerations
Your Xerox 4635 Laser Printing System (LPS) has many unique
standard and optional features which distinguish it from other
Xerox LPS. Your 4635 LPS is capable of running most jobs
created on other Xerox LPS, and can create jobs to print on
other LPS. The “LPS compatibility and comparison” section of
this chapter points out the unique qualities of your 4635 LPS, and
helps you evaluate whether your 4635 LPS running software
version 3A is a suitable backup printer for another Xerox LPS.
In order to ensure your jobs are created and produced with the
highest quality, there are many things you need to consider. The
“4635 user considerations” section of this chapter addresses such
items.
This chapter contains the following major sections:
•
•
LPS compatibility and comparison
4635 user considerations.
LPS compatibility and comparison
The tables in the sections that follow identify what you need to
consider when using your 4635 LPS for printing jobs created on
other Xerox LPS with different software versions. They also point
out those features which are unique to your 4635 LPS. The
tables are not designed to address compatibility issues in an allinclusive manner. Use them to make a high-level check when
you want to know if your 4635 will process and print a particular
job.
Each table addresses a different area of consideration from PDL
commands to paper sizes and stocks. Often there is no need for
any further checking because the tables provide the answer.
Other times they show you where further investigation is
needed, or suggest specifically what you should check, either on
your 4635 LPS or in the print job. You may need to refer to
another manual in your 4635 LPS reference set for detailed
guidance on running a particular type of job or altering a job to
make it compatible with your 4635 LPS.
In order to evaluate whether your 4635 running software version
3A can be used as a suitable backup printer for a print job
created on another Xerox LPS running a different software
version, you must consider many factors. The following is a basic
job compatibility checklist to help you begin the task of
determining if a job will run on your 4635 LPS.
•
Are font character sets required by the job loaded on the
4635 LPS?
•
Are forms required by the job loaded on the 4635 LPS?
XEROX 4635 LASER PRINTING SYSTEM PRODUCT REFERENCE

PRODUCT DIFFERENCES/USER CONSIDERATIONS
•
Is the allocated size of the print file on the 4635 LPS
appropriate for the print job?
•
Is the current forms default on the 4635 LPS appropriate for
the print job?
•
Is the current graphics default on the 4635 LPS appropriate
for the print job?
•
Is the current font default on the 4635 LPS appropriate for
the print job?
•
Does the 4635 LPS have sufficient memory for the print job?
•
Does the Interpress set (Commercial or Publishing)
supported by your 4635 LPS support the printing
requirements of the print job?
•
Does the print job require a finishing device?
•
Does the print job require a configured XPAF, HIP, or SDI
connection?
Using your 4635 as a backup LPS
Tables 5-1 through 5-5 identify particular job features to consider
when printing a job on your 4635 LPS which was created on
another Xerox LPS running a different software version. Each
table contains specific job features which may be encountered,
the projected results when printed on your 4635 LPS, and where
to find further information.

PRODUCT DIFFERENCES/USER CONSIDERATIONS
Comparing LPS print job resolution
Since Xerox laser printing systems have different print resolution
capabilities, it is important to compare the print resolution
functionality of your 4635 LPS and of the LPS the job was created
on. Table 5-8 illustrates the print resolution functionalities of the
Xerox LPS.

Checking JDL compatibility
Job descriptor libraries (JDLs) are collections of compiled job
descriptions which are set up by the user. Many jobs may be
compiled on one LPS and run on another. Table 5-9 shows how
your 4635 LPS handles JDLs from other LPS.

Checking PDL compatibility
Print description language (PDL) commands define the format of
the input media, processing requirements, and the format of the
printed output. Each command has a set of parameters that can
be used to define a print job's characteristics. Table 5-10 shows
the PDL command parameters that your 4635 LPS does not
process. Your 4635, however, processes other parameters
associated with the command.
PDL commands which the 4635 does not process are indicated

PRODUCT DIFFERENCES/USER CONSIDERATIONS
4635 LPS user considerations
This section describes inherent 4635 LPS user considerations.
4635 LPS edgemarking
To ensure consistency across all Xerox LPS printers, the
coordinate system used by all printers is identical. However, the
area upon which an actual image may appear is limited. Because
of this, data which starts near the edge of or off of the physical
page may be lost.
Edgemarking is the placement of marks at or near the edge of
the physical page. To accommodate edgemarking, the system
page must be larger than the physical page.
The 4635 LPS edgemarking capability could be limited if the
system page boundaries correspond to the sides of the physical
page of paper.
If any part of a form element or variable data line is positioned
off the leading edge of the system page (that is, the top edge of
a landscape-oriented page or the left edge of a portrait-oriented
page), the entire data element is not imaged. Refer to figure 5-1.
•
If a line of variable text begins off the leading edge of the
system page, the entire line of text is not printed.
•
If a ruled line begins off the leading edge of the system
page, the entire ruled line is not printed.
•
A line running parallel to the leading edge needs to be
positioned at least half the line thickness inside the leading
edge of the system page in order to be printed. For
example, a bold line is 8 dots thick and it must, therefore, be
positioned at least 4 dots inside the leading edge of the
system page.
•
If any part of a signature or logo begins off the leading edge
of the system page, the entire signature or logo is not
printed.
•
One common cause of print elements accidentally beginning
off the system page is the improper use of the OUTPUT
SHIFT command. This command is used to shift the entire
contents of a page relative to the boundaries of the system
page. When a negative shift value is entered (as is often the
case for the back side of duplex pages), and that value
exceeds the left margin, no text elements will print. When
using a negative value for the OUTPUT SHIFT command, be
sure that it is less than the value of the left margin.

Within system page, data will edgemark
Off system page, data will not print.
To determine whether or not an item has fallen off the system
page, the following formulas may be used in determining the
number of dots (1/300 of an inch) which make up the area
between the leading edge of the system page and the leading
edge of the physical page. For 8.5 by 11 or 8.5 by 14-inch
paper, the formula is:
Printer alignment in scan direction -1
5-18
XEROX 4635 LASER PRINTING SYSTEM PRODUCT REFERENCE
PRODUCT DIFFERENCES/USER CONSIDERATIONS
For A4 paper, the formula is:
Printer alignment in scan direction +69
If any part of an item begins more than this number of dots
before the leading edge of the physical page, the item falls off
the system page and does not print.
Registration shift and skew
The registration of a printed image can appear shifted or skewed
on a page if the sheet of paper is misaligned as it enters the
printer. Because of the design of the LPS feeder, the image
registration on each page can vary slightly both horizontally and
vertically by up to 0.65 mm. The image can also be slanted or
skewed slightly by 3.97 milliradians. (Refer to figures 5-3 and
5-4, Landscape and portrait shift and skew.) Note that the
following figures are the same specifications merely rotated to
show portrait and landscape orientations. The shift and skew
variances described here are within allowable specifications, but
as this can affect the registration of variable data in preprinted
forms and the placement of images close to the edge of the
page, it is important to make allowance for this condition.
Figure 5-3 illustrates the landscape orientation shift and skew.

Paper size
Variable paper size
Page dimensions up to the physical capacity of the feeder trays
may be selected. (The largest feeder tray physical capacity is
14.33 by 17.0 inches; the smallest is 7.0 by 10.0 inches with the
optional Paper Feeding Enhancement Kit installed). At system
generation (sysgen), you can select USLETTER, USLEGAL, or A4;
or you can select “other” and specify any paper size between the
smallest and largest allowed (x by y) in millimeters. 11 by 17
inch/297 by 432 mm Interpress jobs are not supported, however,
your 4635 LPS handles 11 by 17/inch/297 by 432 mm IMG jobs.
The use of the PAPERSIZE command in PDL and the PAPER
command in FDL permits form compilation and job printing on a
size of paper other than the sysgened paper size and allows the
specification of nonstandard paper sizes for those jobs requiring
nonstandard paper.
It is recommended that you sysgen to the largest size paper that
you commonly use. Smaller and less-used paper sizes should be
specified using PDL and FDL commands.
Refer to the Xerox 4635 LPS PDL/DJDE Reference and 4635 LPS
Forms Creation Guide for more information on commands.
System page size
The 4635 maximum imaging area (that is, the system page)
measures 14.33 by 17 inches.
5-20
XEROX 4635 LASER PRINTING SYSTEM PRODUCT REFERENCE
PRODUCT DIFFERENCES/USER CONSIDERATIONS
Virtual page size
The default virtual page size is identical to the physical page size.
If a virtual page size is user-defined, the virtual page is centered
relative to the physical page. A user-defined virtual page may not
be larger than the paper size value; larger dimensions are
truncated.
Error messages
If any part of a print line originates off the system page, the
following message is displayed:
OS6905 DATA ORIGIN OFF PAGE -- CHECK OUTPUT
This message appears only once during a print job. It indicates a
print line origin problem within the form description or an
excessive SHIFT value. Refer to the Xerox LPS Forms Creation
Guide and the Xerox 4635 LPS Message Guide for more
information.
Deletions
The 4635 printer utilizes the newest xerographic advancements,
providing good solid black print quality and spot control.
However, in certain circumstances, there is a possibility that
toner from the photoreceptor may not completely transfer to a
sheet of paper before it is fused and sent to the output bin. This
occurrence is known as a deletion. Generally, deletions will
result in a small area of the printed page appearing lighter than
the rest of the page. For example, a few letters of a word may
appear lighter than the rest of the word.
To help reduce the occurrence of deletion, the 4635 printer has
been fitted with a four-segment transfer blade which presses the
paper onto the photoreceptor during toner transfer. This blade
is automatically activated based on the paper size setting in the
job descriptor and does not involve any operator interaction or
loss of productivity.
There are two different transfer blades: one for 60Hz systems and
one for 50Hz systems. Each blade can adjust to four paper size
lengths as follows:
60 Hz blade: 11, 11.69, 13, and 14 inches (279, 297, 330, 356
mm)
50 Hz blade: 10, 11, 11.69, and 13 inches (254, 279, 297, 330
mm)
Thus, if you switch from 8.5 by 11 inches/216 by 279 mm to U.S.
legal (8.5 by 14 inches/216 by 356 mm), the 11 inches/279 mm
segment is utilized first, then the additional blade extension to
14 inches/356 mm is activated automatically when the legal size
paper is encountered.
Two points to note:
•
For page lengths in between the preset blade lengths, there
may be some deletion on paper that extends past the blade.
The rate of occurrence of deletions varies widely, depending
on paper stock, and should be tested. Also, note that no
XEROX 4635 LASER PRINTING SYSTEM PRODUCT REFERENCE
5-21
PRODUCT DIFFERENCES/USER CONSIDERATIONS
deletion will be noticed if no data is printed on the portion
of paper that extends past the blade.
If you frequently use non-standard size paper, a custom
transfer blade kit is available for installation on your printer.
For more information on the custom transfer assist blade,
refer to the Xerox 4635 LPS Operator Guide.
•
The activation of the blade is timed to place it on the lead
edge of the sheet of paper as it moves through the system.
The placement of the activation can vary with the actual
speed of paper. Therefore, performance may demonstrate
some deletions on the lead 0.25 inches/6mm of the page. In
particular, solid black lines on the lead edge of the page
should be avoided if this is a major concern to you.
A consideration resulting from the very solid black characters that
the 4635 LPS can print is that toner on the lead edge of the
paper may cause the sheet to stick to the fuser, due to the
consistency and solidness of the toner. In order to eliminate
fuser jams caused by this condition, the system uses a digital
screen to lighten automatically any solid areas printed in the first
0.25 inches/6mm of the lead edge. If the solid areas are small,
the amount of screen is barely noticeable, if at all. However,
with very large solid black areas, the effect may not be
acceptable. The system does provide an override using the Lead
Edge Screen window at the PC UI, or the EDGE command
entered at the command line. This window or command allows
you to enable or disable the lead edge screen; however,
overriding the screen in this manner is likely to increase fuser
jams.
For particular applications, it is recommended that you run test
prints both with and without the screen to ascertain which mode
is most appropriate for you.
For more information on the Lead Edge Screen window, refer to
the Xerox 4635 LPS Operator Guide or the Xerox 4635 LPS PC
User Interface Reference. For more information on entering the
EDGE command at the command line, refer to the Xerox 4635
LPS Operator Guide or the Xerox 4635 LPS Operations
Reference.
Print Darkness
The 4635 LPS provides you with capabilities for tuning your
output print quality to meet the particular needs of your
application. The Print Darkness window at the PC UI is a feature
which allows you to adjust darkness of printed characters and
images. Print darkness is a scale from 1 to 9, which either
darkens or lightens the image, as well as broadening or thinning
the look of various characters. The nominal setting is 5, which
provides the optimal mix of darkness and line thickness.
It is recommended that you test the Print Darkness feature to
determine the best setting for your site or application. For more
information on the Print Darkness window, refer to the Xerox
4635 LPS Operator Guide or to the Xerox 4635 LPS PC User
Interface Reference. For more information on entering the
DARKNESS command at the command line, refer to the Xerox
4635 LPS Operator Guide or the Xerox 4635 LPS Operations
Reference.

PRODUCT DIFFERENCES/USER CONSIDERATIONS
Note: On 4635MX systems, Print Darkness is restricted to only
level 5 when printing in the MICR mode.
Interpolation and scanned images
The 4635 LPS accepts 300 spi data and prints it using a 600 spi
dual beam raster output scanner (ROS). To convert 300 spi input
data to 600 spi print output, the system uses an interpolation
algorithm to smooth lines and improve the quality of 300 spi
fonts and line art.
Note that the interpolator does not always improve scanned halftone images. The Xerox 7650 Pro Imager Scanner has several
screens which attempt to maximize the effect of interpolation on
the quality of half-tones. However, in order to utilize these new
screens you must re-scan previously scanned images. The
relative level of improvement needs to be evaluated by you on
your own half-tone images.
Switching paper size and feed modes
The 4635 LPS system operates in a multiple-pitch print mode: 7
pitch to 3 pitch.
The multi-pitch feature allows your 4635 LPS to adjust the pitch
mode according to the width of the paper you are using. Table
5-2 shows the relation between the pitch mode, the maximum
width of the paper being fed in a long edge feed mode, and the
page per minute (PPM) rate. Long edge feed mode means the
sheet is fed into the paper path with its long edge first.

* 8 pitch is enabled only with the optional Paper Feeding
Enhancement Kit installed
For papers whose widths range from 8.66 to 9 inches, the 4635
prints with slightly reduced productivity at 135 pages per minute,
with seven-page images per photoreceptor revolution.
Productivity is slightly reduced because in order to maintain print
speed for papers of this size, the system must temporarily
suspend xerographic print quality checks. The 4635 maintains
the highest print quality by periodically reducing printer output
to perform xerographic print quality checks. After a print quality
check, the system automatically resumes printing at full
productivity.

5-23
PRODUCT DIFFERENCES/USER CONSIDERATIONS
Cleaning time between pitch mode changes
Because the xerographic process places toner images on the
photoreceptor belt, it is necessary for the printer to clean the
system completely when switching to different modes. This
cleaning process ensures that unprinted toner from one pitch
mode is not deposited on sheets running in the other mode.
This cleaning process requires approximately 25-30 seconds,
during which time the system “dead cycles” before printing
again. During this time, areas of the printer are running, but
paper is not fed through the system.
Specialized papers
The 4635 printer handles paper differently from the 9790 and
other Xerox LPS. Paper sensors and the paper path are not the
same from one printing product to another. An application
running special papers on a 9790, for example, may yield slightly
different results when printed on the 4635 LPS. Therefore, it is
recommended that you test applications that use specialized
papers to ensure that output is satisfactory.
Pay special attention to the following materials:
•
Die cut paper (paper with windows or areas cut out) must be
tested to ensure that the sheet registers properly with paper
sensors.
•
Multiple-thickness materials may cause stacking problems.
Such problems may be alleviated by using the Bin Limits
window or command to limit the number of sheets that can
be stacked in a bin.
For information on the Bin Limits window and command,
refer to the Xerox 4635 LPS Operator Guide or the 4635 LPS
PC User Interface Reference
Refer to Helpful Facts About Paper for more information on the
selection, storage, and handling of papers for your 4635 LPS.
LAN support
The 4635 now supports the installation of a LAN PWB in the
PCUI to upload audit logs to a remote system for processing.
With this feature installed, any time an audit log is completed it
will automatically be transmitted over the LAN to a remote
system. Xerox will provide the software for the 4635 to support
the feature. It is the customer's responsibility to provide the
circuit board and any related software and cables.
Note:
5-24
The PCUI must be logged on to the LAN for an audit log to be
uploaded to a remote system. If the log on has not been
accomplished, an error message will be displayed at the
completion of each audited report.

4635/4635MX Audit log record
Overview
This document contains the public record format
definitions for the Xerox 4635 / 4635MX audit logs. There
are two types of audit log files. The first is the Master
Audit Directory file (.ALM). The second is the Audit Log
Data file (.ALG).
The Master Audit Directory file provides a mapping from
report names (as specified by the BTEXT RNA parameter)
to the Audit Log Data file's DOS filename. It also contains
selected summary information.
The second file type is the Audit Log Data file. Using the
DOS file name returned from the Master Audit Directory
file, you can select the following record types from the
Audit Log Data file: Log Header, Page Detail, Waste
Management and Operations Log.
The following record formats used in conjunction with the
BTRIEVE record management software documentation will
enable the customer to programatically access Audit Log
data.
Master audit directory
This file contains an entry for each report that is audited. It
maps report names that are displayed to the operator to
DOS file names and contains copies of certain data fields
from each audit log file.
This redundant data is included to enhance performance
when querying a number of logs. For example, a list of
logs with their start dates, stale dates and error status
could be prepared without referencing the Audit Log Data
file for these reports.
The scope of the Master Directory includes the in-process
log file as well as completed reports. Logs that have been
deleted from the PC UI with the "Audit Log
Administration" window will not appear in this file.

AUDIT LOG RECORD FORMAT
Audit log data
Copying an Audit Log with the Log Save function will create a
uniquely named *.ALG file that contains only the log data for that
report. This is the file name that will be associated with the user
report name in the Master Audit Directory file.
This file contains several types of records, which share a common
set of keys. One of these keys is a Record Type field which
specifies the structure of the remaining data in the record. When
accessing these records, ensure that your buffer is at least as
large as the longest possible record, the Log Header, which is
361 bytes long. Once the record is read you can use the
common key structure (section "a" of each record type) to
access the Record Type field. The value of this field indicates
which record structure to use in accessing the data in the
remainder of the record.

Key audit report calculations
This section provides additional information on how some
of the key fields shown are calculated.
Good sheets fed by source
Total good sheets fed
The total number of good sheets fed is the sum of all of
the values in the good sheets fed array in the log header
record.
Good sheets delivered by destination
The number of good sheets delivered to a particular
destination correspond to the values in words 1-6 in the
good sheets delivered array of the log header record as
follows: S = sample tray, A = bin A, B = bin B, C = bin
C, D = bin D, E = bypass transport.
Waste sheets fed by source
Total waste sheets fed
Waste sheets delivered by destination
A-10
The number of good sheets fed from each tray is stored in
order in the good sheets fed array of the log header
record. Trays 1-7 correspond in order to words 1-7 of the
array.
The number of sheets fed from each tray is stored in order
in the waste sheets fed array in the log header record.
Trays 1-7 correspond in order to words 1-7 of the array.
The total number of waste sheets fed is the sum of all of
the values in the waste sheets fed array of the log header
record.
The number of waste sheets delivered corresponds to the
values in words 1 and 7 (sample tray and purge tray) in the
waste sheets delivered array of the of the log header
record. The sheets removed value is obtained by
subtracting the sum of words 1 and 7 from the total waste
sheets fed value.
